Perplexity

Extract specific legal provisions reliably.

The `get_section` tool pulls the exact text you need from any Act. Since every response is validated against a schema, your agent never gets hallucinated fields or corrupted data. This makes it perfect for compliance agents that can't afford even a single bad character in their output.

Scope out entire legislative documents.

Want to know the structure of an act? Use `get_table_of_contents`. The response is typed, so your agent knows exactly what kind of list it's receiving. If you need a general overview, run `search_legislation` to get a validated list of relevant acts and instruments.

Find laws by topic or date.

Need to search for something specific? Run `search_by_subject`. The resulting data is immediately checked against Pydantic models, guaranteeing the output format your agent expects. You can also check historical context with `get_legislation_by_year`.
